The applications of Epithelial Cells

Question

The principle function of epithelial cells is to provide a protective layer for the organ they enclose but also provide other biological functions including secretion, selective absorption, filtration, protection and detection of sensation. The dysfunction of epithelial cells leads to a variety of diseases, infections and tumors. Therefore, epithelial cells are used in multiple research areas such as physiology, immunology, cytobiology, development and reproductive biology, molecular biology.
